Stabilizes blocked-by overlap stamping in the scheduler and adds a standalone `recover-stale-blocked-by` utility script to clear stale upstream blockers, with corresponding scheduler tests and architecture documentation.
Fusion-Task-Id: FN-3899
The merge implements post-merge model resolution, using the merger's own session model for executing post-merge prompt workflow steps instead of falling back to executor model defaults. Tests cover the resolution hierarchy, and documentation clarifies the precedence order for downstream consumers.
Fusion-Task-Id: FN-3905
Adds bounded room thread context and mailbox reply context to the chat system, implemented in `agent-tools.ts` with corresponding dashboard room handling in `chat.ts`; includes expanded test coverage for both modules and updated documentation in `agents.md`.
Fusion-Task-Id: FN-4004
Implements worktree database hydration for the executor (`worktree-db-hydrate.ts`), enabling the task executor to restore its database state from a worktree on resume, with integration in `executor.ts` and comprehensive test coverage across the new module and worktree scenarios. Documentation and a
Fusion-Task-Id: FN-3841
FN-3979 adds test coverage validating the FN-3834 overlap detection fix: Step 1 introduces overlap validation tests in the merger and self-healing test suites, and Step 2 cleans up a type-safety issue in the overlap test.
Fusion-Task-Id: FN-3979
Merged FN-3834 to add a no-op merge recovery flow to the merger, including a branch-ahead detector, short-circuit logic to exclude no-op merges from the mergeable sweep, and finalization of no-op review tasks — backed by substantial test coverage across merger and self-healing modules.
Fusion-Task-Id: FN-3834
Adds heartbeat scope-discipline guardrails to the executor's heartbeat procedure, ensuring agents stay focused on their assigned scope rather than drifting to unrelated work. Includes tests for the updated heartbeat prompts and documentation in agents.md, shipped as a patch.
Fusion-Task-Id: FN-3884
Adds task lineage storage infrastructure (FN-3990 Step 2), introducing a dedicated `task-lineage.ts` module and related types to track task identity and association relationships, with corresponding database schema and store support plus tests and documentation for the lineage reconciliation process
Fusion-Task-Id: FN-3990
Completes FN-3976 by reclassifying GitHub import action gating in the engine's `gating-classifications.ts`, updating documentation in `docs/agents.md` accordingly, and adding test coverage across four gating test suites.
Fusion-Task-Id: FN-3976
Refined self-healing recovery logic for tasks that lack a `fn_task_done` signal, aligned detection in the engine with matching test coverage and architecture documentation for the recovery behavior.
Fusion-Task-Id: FN-3962
- Add self-healing recovery to detect in-review tasks that lost their worktree and clear stale blockedBy state
- Extend restart recovery coordinator handling and tests for missing-worktree classification behavior
- Add focused self-healing and restart recovery test coverage for the new recovery path
- Document missing-worktree review recovery behavior in architecture docs
Fusion-Task-Id: FN-3972
Adds scheduler heartbeat timer reconciliation with automatic self-healing when timers drift, including tests for tracked-only monitor recovery and documentation in the agents reference.
Fusion-Task-Id: FN-3958
Implements approval guards for agent provisioning (FN-3791), adding policy-gated create/delete flows with dedupe logic, CLI tool alignment, engine run-audit coverage, and corresponding test suites, plus documentation updates and a regression fix for verification/tool docs sync.
Fusion-Task-Id: FN-3791
Adds test coverage for task environment propagation through the spawn flow, covering child agents inheriting task env, workflow step task env, and spawn hook env isolation cases in `pi-create-fn-agent.test.ts`, with minor additions to `executor-step-session.test.ts` and `executor-pause.test.ts`.
Fusion-Task-Id: FN-3968
Adds executor runtime environment support to the plugin system, enabling plugins to contribute environment variables that get injected into executor commands. The implementation includes new plugin types (`ExecutorRuntimeEnvPlugin`), aggregation in the plugin runner, thread-through into executor com
Fusion-Task-Id: FN-3767
Adds a `delegate_override` flag to the `delegate_task` tool that allows executor-role tasks to be assigned to non-executor agents. The override is persisted as metadata in the extension and honored by the heartbeat inbox guard, with test coverage across engine, core, and CLI packages plus updated do
Fusion-Task-Id: FN-3957
- Add core outage schema and mesh replay contract types, with CentralCore/CentralDB support for queue and snapshot persistence
- Expose runtime replay hooks in engine health monitoring and peer exchange paths to drive outage recovery flows
- Expand protocol and architecture docs for shared mesh replay behavior and finalized contract expectations
- Add regression tests across core and engine for queue sequencing, snapshot contracts, and replay integration
Fusion-Task-Id: FN-3960
The merge completes Step 1 of agent provisioning approval followthrough, executing provisioning actions when approval decisions are made, with supporting documentation in AGENTS.md and docs/agents.md. Test coverage spans provisioning policy, approval routes, gating classifications, extension integra
Fusion-Task-Id: FN-3956
Hardens merge recovery logic (FN-3951) with guards against invalid state transitions during terminal merge errors, backed by new tests in `merge-error-recovery.test.ts` and `self-healing.test.ts`, and documented in the task management docs.
Fusion-Task-Id: FN-3951
Completes FN-3939 audit work for PR #59 residual defects by refactoring the mission execution loop in the engine (halving its complexity), adding self-healing test coverage, and wiring in task workflow route improvements. Retry and validation behavior updates are documented in the changeset and skil
Fusion-Task-Id: FN-3939
Merged agent provisioning approval policies into the engine with guard controls that restrict which agents can be created and by whom, integrated through the CLI extension and core policy definitions.
Fusion-Task-Id: FN-3953
The merger gains a safeguard that automatically stashes work when a finalize-reset leaves orphaned records, preventing merge-state corruption. Core exports the new orphan record type, project-engine wires the safeguard, and documentation traces the provenance flow; tests were added for the recovery
Fusion-Task-Id: FN-3932
Adds heartbeat scope guidance to the agent-heartbeat module with corresponding tests, helping agents understand when and how to scope their heartbeat work.
Fusion-Task-Id: FN-3946
Adds GitHub tracking controls to the TaskDetailModal with corresponding test coverage, and documents the feature in the dashboard guide and task management docs.
Fusion-Task-Id: FN-3940
Adds a new restart recovery coordinator (FN-3934) to manage task recovery on agent restart, including the core coordinator class, tests, and integration into the in-process runtime; also documents the coordinator in AGENTS.md.
Fusion-Task-Id: FN-3934
The merge fixes triage planning model session key recovery in the engine, enabling the triage agent to properly use default model keys when resuming planning sessions. Tests were added to `triage.test.ts` to assert the correct behavior.
Fusion-Task-Id: FN-3931
Adds auto-recovery for merge deadlocks when candidates have already been merged on main (FN-3857), including tests, documentation updates in AGENTS.md, and a patch changeset for the `@runfusion/fusion` package.
Fusion-Task-Id: FN-3857
Extends AgentRuntimeOptions and AgentOptions with an optional
systemPromptLayers field (SystemPromptLayers) for cross-session prompt
caching. DefaultResourceLoader now uses the stable layer as
systemPromptOverride and the dynamic layer as appendSystemPromptOverride
when layers are provided, falling back to the flat systemPrompt string
for backward compatibility.
